Helpful guide indeed! Am loving mobbing all the mobs to death with a horde of undead!
Would just like to add that I found a fairly useful unique item for this (and other corpse explosion using builds), they are sacred gloves called "Howl from Below", and their unique property adds % damage to corpse explosion damage, and turns them into sprinting self-exploding corpses that seek the closest (I think) enemy to blow up. Helpful for when corpses are spread around and would otherwise leave puddles laying about that are less than helpful
Ah, found the page for the very item here
